如何將WPF富文本框變爲字符串

Question

我看到了如何設置WPF富文本框RichTextBox Class。

然而，我喜歡將它的文本保存到數據庫中，就像我曾經在Windows Forms中那樣。

string myData = richTextBox.Text; 
dbSave(myData); 

我該怎麼辦？

在MSDN RichTextBox參考的底部，有對How to Extract the Text Content from a RichTextBox

一個鏈接這將是這樣的：

public string RichTextBoxExample() 
{ 
    RichTextBox myRichTextBox = new RichTextBox(); 

    // Create a FlowDocument to contain content for the RichTextBox. 
    FlowDocument myFlowDoc = new FlowDocument(); 

    // Add initial content to the RichTextBox. 
    myRichTextBox.Document = myFlowDoc; 

    // Let's pretend the RichTextBox gets content magically ... 

    TextRange textRange = new TextRange(
     // TextPointer to the start of content in the RichTextBox. 
     myRichTextBox.Document.ContentStart, 
     // TextPointer to the end of content in the RichTextBox. 
     myRichTextBox.Document.ContentEnd 
    ); 

    // The Text property on a TextRange object returns a string 
    // representing the plain text content of the TextRange. 
    return textRange.Text; 
}
